, after the second treatment I caught up with the exterminator who said that there was visible evidence at the first treatment, but by the second treatment they were gone. I have now finished the last treatment and everything went very well. The Manager inspected all of the units around mine and found that they hadnt spread, which was lucky. The management of the building was very helpful with the process, they helped me get plastic to wrap up what i needed to throw away, and gave meupdates with each extermination. Im happy to be bed-bug free now!!
